COAL-STOVE.

Specification forming part of Letters Fatent No. 49,33 3, dated `AugustB, 1865.

To all whom 'it may concern panying drawings, which make a part ot' thisspecification.

Like letters represent and referto like or corresponding parts.

Figure lis a vertical section ot' my improved base-burning coal-stovefrom side to side at right angles with the exit-pipe, and showing thecoal-supply reservoir or chamber surrounded with an air-chamber, andalso showing the tire pot or chamber containing an annular chamber, andimmediately below the said supply-reservoir and its chamber the outer orradiating chamber, the fire-grate, the 'ash-pit, and the iue or tlues inthe base of the said stove, and each morefully hereinafter described andset forth. Fig. 2 is a vertical section of lthe said stoves containingthe said improvements and on a line from front to rear through theexit-pipe. Fig. 3 is a horizontal section on the dotted line A A and B Bof Figs. l and 2. Fig. 4 is a horizontal section on the dotted line C Cand D D of Figs. l and 2. Fig. 5 is a horizontal section on the dottedline E E and F F of Figs. l and 2.

The nature of my said invention and improvements consistsin theemployment of a self-seeding or coal-supply reservoir or chamber, whichshallbesurrounded by an air-heating chamber of any convenient shape orcapacity, and into which cold air shall enter from 4the room where thesaid stove may be used through a supply-tube constructed for thatpurpose at or near the bottom of said annular air-heatin g chamber, bymeans of which the air enters said chambers and there becomes heatedthrough, and by means oi'an outer casing, which casing in part formssaid annular chamber,

' and rising therein it escapes into the room to be warmed or heatedthrough openings at the top of such air-heating chamber constructed forthat purpose; or it may be made toV enter the radiating chamber throughand by means of a valve or damper at or near the top of the saidchamber, and thence be thrown down and upon the fire or ignited coal toaid combustion, in the manner substantially as herein described and-setforth. l

Italso consists in the employment of aiirepot constructed with `anannular air-chamber, formed between an inner and outer plate `or casing,into which air is admitted through an opening in front and in rear ofthe stove, in the manner substantially as herein "described and setforth.

To enable others skilled in the art to which my invention relates tomake `and use the same, I will here proceed to describe thereonstrnctionand operation thereof, which is as follow, to-wit: l

I construct the base and outer cylinder of my improved stove in `anyconvenient and-substan tial manner. The {ire-pot A is made either ofcast-iron or lire-brick, as may be deemed best; but I generallyprefereast-iron lined with tire-brick up to within a short distance ofthe perforations through which atmospheric air is admitted to the re inthe :fire-pot, as shown at a, Figs. 1 and 2.

There is an air-chamber entirely surrounding the fire-pot, as shown `atl, Figs..1 and 2. This annular chamber maybe of any capacity desired,and there maybe-as many-openings or perforations communicating with`thetirechamber as may be deemed best, through which atmospheric airpasses into the said fire-chamber to aid combustion in the consumptionof the gases and smoke, or as much thereof as may by such means beburned or consumed. Cold air is admitted into said air-chamber throughthe openings or dampers B `and-B in the front and rear ofthe stove, andpasses Vup through said airch amber and through the said perforations,thereby burning the gases, smoke, and othery combustible material iarising `from `the surface of the fuel inthe fire-pot, asaforesaid, andalso preventing in a great measure the too rapid burning out of theinner part of said re-pot if constructed of cast-iron only,

and it' of lire-brick the same result is reached 'relative to suchbrick. l The said self-feeding reservoir or chamber I construct ofcast-iron or other suitable material, and of any size or strength deemedbest, and may extend down to near the top of the said fire-pot, ifdeemed best so to do. G, Fig. 2, is opening or damper in the back partof the stove, through which v2 and 5, ator near the top ofsaid ann/ularchamber D, may then be opened, so that such air .so heated shall bethrown into the radiatingchamber I, Figs. 1, 2, and 4, and thence downthe same into or upon the-fire or burning inaterial in the vsaid lirepot or chamber A, andv thereby aid combustion. Thevheat arisin-g fromthe fuel in the combustion-chamber or fire-pot Ipasses up and surroundsthe said air-heating chamber D surrounding the said coal-supplyreservoirchamber, and thence into the iiues in the ba-se of the stove throughtheopeniugs GG,

Figs. l and 3, and thence in the line of the draft at the bottom of thevertical exit-pipe J, Fig. 2.

-When the damper Kin the back connectingpipe, L, is closed the draft isturned down Ward and passes down the outer side ofthe fire-pot orcombustion-chamber into the chamber in the base of the stove, and thenceinto the back pipe through the openin g M, Fig. 2, as aforesaid.

To use my said improved stove, a fire is built in it in the usual mannerou the grate N, Figs.

i 2and 3. The coal is then put in the said feeding chamber or reservoir.E through an openingin the top thereof, which is then closed. The draftis admitted to the combustion-chamber and to the ire therein through thegrate N, in the usualmanner, by means of a sliding damper, which is inthe door that closes or opens into the ash pan or chamber, which issituated below the iregrate, and which receives the ashes from thefire-grate when the stoveis in operation. By opening the pipe-damper Kthe direct draft is had, which, when closed, sets into operation thecircuitous draft, as aforesaid described. All dampers must be closed inorder to, stop all draft when desired. By the means hereinbeforedescribed l am enabled to construct a stove containing a great amount ofheating and radiating surface, which is very desirable in parlor andlike stoves 5 and by the aid of my said self-feedin g chamber orcoal-supply reservoir will be obviated the necessity of too frequentfilling the stoye with coal. The said feeding-chamber being once filledwith coal will last from thirty to sixty hours, feeding the re iu thecombustion-chamber as fast as it is required by the burning orconsumption ofthe coal within the same.

It will be seen that admit atmospheric air into the said chambersurrounding the said coalsupply reservoir at or near the bottom of thesaid chamber, and, by means of and through a tube passing therefromthrough the radiatingchamber and through the outer cylinder or casingwhich surrounds and forms the space between it and the casing whichforms the said ar-heatin g chamber around the said coal feeding orsupply reservoir, into the room Where such stove is used. Such air,entering the said heating chamber in the manner aforesaid, arises in andentirely Iills the said heatingchamber with fresh air, and, heating thesame to a desirable temperature, it is thrown into the room to bewarmed, while at the same time it contributes largely to preserve theimmediate lower end of such coal-supply chamber or v reservoir, and alsoprotects and preserves the said casing by which the'said air-heatin gchamber is formed, as aforesaid, from undue wear or destruction by orfrom the heat in and arising from the fire-pot or chamber of combustionbelow, as aforesaid.

By placing a tin or sheet-iron tube upon the top of my said stove of asize sufficient to cover the said openings in t`1.e top of the said airheating-chamber, and continuing the same to the room in the next storyabove that Where the said stove is used, such room or story may be thuswarmed.

Having thus described the construction and operation of my saidinvention, what I claim, and desire to secure by Letters Patent of theUnited States of America, is-.

l. The employment of the said self-feeding reservoir or chamber, E,surrounded by the air-heating chamber D, with cold-air-supply tube Oi,arranged and combinedwith a baseburningcoal-stove,in themannersubstantially as and for the purpose herein described and set forth.

2. The employment of a fire-pot or combustion-chamber constructed withan annular hotair chamber, with openings B B, arranged in the mannersubstantially as herein described and set forth.

3. The combination of the damper H with the openings or dampers o o inthe coal-supply reservoir or chamber and said air-heating annularchamber D, in the manner substantially as and for the purpose hereindescribed and set forth.

In testimony Whereofl have, on'this 1st day of May, A.-D.'1865, hereuntoset my hand.
